We’ve already declared Step Up Revolutionthe guilty pleasure movie of the summer, and now we can show you one of the reasons behind our pick: The ultra-hot chemistry between the film’s stars, Ryan Guzman and Kathryn McCormick. According to the film’s director, Scott Speer, whom we spoke with last week at the film’s press junket in L.A.: “They fell for each other, which is always a huge help.” Added producer Adam Shankman, “Both are really talented and both are really, really nice, and I hadn’t seen that since we cast Channing Tatum and Jenna Dewan [in the first Step Up film]. And we know what happened there — they’re married.”

I walked into see Step Up Revolution with zero expectations, and found myself cheering and clapping through the whole thing and – dare I confess – getting choked up at one moment. My 3-D glasses fogged up, guys – it was that good. And also a little bad — in the best way possible. The dancing, the script, the love story and the wonderful cheesiness of it all earned it my vote for Best Guilty Pleasure Movie of the Summer. Not convinced? Here are five reasons why you should be.

Reality-show contestants come a dime a dozen, and once their shows are off the air, we’re so busy watching the next competition, we often forget to see whether the winners go on to make it in their chosen profession. For every Carrie Underwood and Jordin Sparks, there are dozens of Taylor Hicks and Nikki McKibbins. But one show seems to be the exception to the rule: The alumni (not just winners) of So You Think You Can Dance show up everywhere: In music videos, on Broadway, on tour with pop stars, on Glee and, this weekend, in Step Up Revolution. When VH1 caught up with the movie’s star, Kathryn McCormick (third place in season 6) and co-star Stephen “Twitch” Boss (season 4’s second-place dancer), we asked how the show contributed to their success.

“[SYTYCD alums] have the mindset that just because they’ve been on the show, nothing is going to be handed to them,” explained freestyle dancer Twitch, who also appeared in Step Up 3D. “They still have to create their opportunities. And for the things that are presented to them, you still have to deliver. So no matter what, even with your exposure on the show, you still have to put your work in it. You still have to continue to pay your dues. The show gives you a rep, yes, it does. And it gives you that exposure, yes, but you still have to deliver on your end of the deal.”

Step Up Revolution is the latest dance film in the now-iconic Step Up franchise, which we can all thank for giving us the glory that is Channing Tatum’s taut backside. The new movie is a romance (yay) set in Miami (caliente!), with Kathryn McCormick as an aspiring dancer who falls in love with a sexy dance mob leader, played by Ryan Guzman. To celebrate, the stars of the film are leading the internet in a virtual flash mob, and they need you to dance your little hearts out on video for them. Film and tweet your moves using the hashtag #stepupmob and you may be featured in the new music video for Timbaland‘s “Hands In The Air.” Sounds fun to us!
